1 claim. (o1. 14s- 122) This invention relatesto improvements in ear corn crushers, the general object of the invention being to provide means for agitating the ears of corn being, fed to the ears slipping away from the rolls.

Another object of the invention is to provide a baiile plate to prevent clogging ofthe ears above the crushing rolls. s 3.0 This invention also consists Vin vcertain other features of construction and'in the combination and arrangement of the several parts to be here-J inaiter fully described, illustrated in theaccompanying drawings and specifically pointedout in the appended claim. l

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, rand inA 51,0 whichz- JQ f l Figure 1 is an elevation of a part of a crushing machine constructed in accordance with this invention. I Y Fig. 2 is a similar View but lookingtowardthe sides having the gears and chain andsprockets arrangementthereon.

Fig. 3 isa vertical sectional View through Fig. 1. Fig. 4 is a vertical sectional view through Fig. 3. Fig. 5 is a sectional View through'the beater shaft and showing the means for connecting the blade forming member thereto. n

' Fig. 6 is a perspective View of the bafe.

' Fig. '7 is a View of one of the'blade forming members. n Y Y In these drawings the numeral 1 indicates the hopper of a crushing machineand the ilettersA and B indicate the crushing rolls located therein. Each roll comprises a number of toothed wheels 2 placed on a shaft 3 and held in spaced relation 1o by the spacers 4. Gears 5 are placed on the shafts 3 and mesh witheach other, and one of the shafts is rotated by a chain drive 6 or other means in a direction to cause the rolls to rotatel toward each other as is usual, so

5 crush and break up ears of corn passing between Y them. This device can be used on Crushers thatV use either one or two rolls. I

In carrying out our invention, we provide a baiiie plate 7 which has a hooked part 8 at one end 5o thereof, fitting over the upper edge of one side wall of the hopper andthis plate extends for-` wardly and downwardly over a part of the roll B. A shaft 9 is journalled in the hopper'above the Y y roll A and is rotated from the shaft vof the'roll ABA by the chain 10 and the sprocketsll, one of'wliich is attached to the shaft 3 of the roll'B andthe l other one is attachedto the shaft 9; lThis. shaft 9 carries a plurality of blades Vor beaters 12, each the crushingirolls, and to 5 force the ears toward the .rolls and to prevent'v that the toothed wheels will that thisV central part hes at right angles to the blade forming end parts.

This vcentral part is' bent to semi-circular shape asl shownY at .13 ofthe shaft. Eachfpartis held to the shaft by aV U-shaped clip 14 which has holes in its limbs for passage Aof, theshaft with the Asemicircular part 3 of the bar passing between the limbs and the bight part of the clip carries a set screw 15'which clamps the semi-circular part 13 to'the'fshaft as 'clearly shown in Fig. 5.V

Thus the blade forming portions of the bars are so positioned that Vtheir edges will engage the` ears of corn, and' these blades willy act'to cause the ears to contact with the roll'B'and in this manner force the ears down through the The blades also'act as agitating means'VA rolls.

to form a recess to receive partv l,

for the ears of corn, to bring the earsinto direct y contact with the rolls, thus acting asa force feeder and. preventing the ears yfrom slipping l `away the toothed wheels as they will do par-l ticularly when the toothed wheels are somewhat dull. Y

Thus the invention will materially increase the capacity ofthe crushing machine, and thelbaie jplate will prevent bridging or clogging of the `ears of corn, which happens in crushing machines of this type.y y y Thisdevice provides for a continuous and uninterrupted feed of the ears to the Crushers.

It is thought fromvthe foregoing description ythat the advantages and novel features rwill be jreadilyl apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the `appended claim.

' Having thus described our invention,l .what we claim as new iszfy In an ear corn crusher, apair of crushing rollers, means for rotating the rollers'towards* each other, a shaftrotatably arranged above one of the rollers, blade-like members arranged in groups on the shaft with the groups spaced apart,V vmeans for rotating the shaft in an opposite direction from the direction of rotation of the roller over which it is placed, whereby the bladelike members will force the ears of corn towards .the otherroller, and a downwardly and inwardly sloping baille plate locatedabove and spaced from said other roller. l
